For all of you with incubators. I have a computer UPS "uninterruptable power supply" that i plug my bator in. I took out the small battery and wired one of my 12v 115 amp hour deep cycle boat batteries to the unit. Now i have no worries about losing power. The battery can run my bator for around 4-5 days. Of course i have 3 batteries and can switch out if needed, but i never have had to do that.
